Abstract:

Machine-to-machine (M2M) communications in cellular networks enables Internet of Things in the macro geographical regions and is a promising technique in next-generation wireless networks. In this paper, we study energy-efficient clustering
design in cellular networks to maximize the overall network battery life time.

Abstract:

As a key enabler of Internet of things, cellular
network based Machine-to-Machine (M2M) communications have
been growing rapidly in recent years, being used in a wide range
of services such as security, metering, health, remote control,
tracking, and so on. A critical issue in M2M communications
is the energy efficiency as typically the machine devices are
powered by batteries of low capacity and thus, it is the key to
optimize their consumption.

Abstract

An innovation has a number of effects on business networks, actors, their roles and activities. Mobile payment can serve as a good illustration of that. The main aim of the paper is to identify what kind of effect innovative mobile payment services have on business networks in retailing. Several of IMP tradition approaches have been applied for the analysis of findings: (i) actors, resources, and activities (ARA) framework was used to model business relationships, and (ii) a conceptual model for studying innovation in networks. Impact of mobile payment in the retail industry has been analyzed from the perspective of interdependency, dynamism, and variety.

Abstract: Predictions for wireless and mobile Internet access suggest an exponential traffic increase, particularly in in-building environments. Non-traditional actors such as facility owners have a growing interest in deploying and operating their own indoor networks to fulfill the capacity demand. Such local operators will need spectrum sharing with neighboring networks because they are not likely to have their own dedicated spectrum.

Abstract: Heterogeneous network (HetNet) deployment strategies have the potential to improve the energy efficiency of mobile access networks. One key aspect to consider in HetNets is the impact of the power consumption of the backhaul, i.e., the overall energy efficiency of a HetNet deployment is affected by the backhaul technology and architecture.
